"Hyangcheola" is a new japonica rice variety developed as a cross between "Joryeong" and "Seolhyangchal" by the rice breeding team at NICS in 2014. The heading date of "Hyangcheola" is July 28 in the middle plain area, which is 8 days earlier than that of "Hwaseong." "Hyangcheola" has a 76 cm long culm, which is 8 cm shorter than "Hwaseong" and has 86 spikelets per panicle. The viviparous germination rate of "Hyangcheola" was 27.9%. It showed resistance to stripe virus but susceptibility to bacterial blight (K1, K2, and K3 races), dwarf and black streak dwarf viruses and planthoppers. The milled rice of this variety exhibits translucent and medium short grain shape. The protein content of "Hyangcheola" was 8.2%, which was 1.5% higher than that of "Hwaseong." "Hyangcheola" is a rice with a fragrant aroma. The content of iron in 100 g of brown "Hyangcheola" rice was 15.12 mg, which is 3.69 mg higher than that of "Hwaseong," and the zinc content was 32.24 mg, which is 8.75 mg more than that of the comparative variety "Hwaseong." The average milled rice yield of "Hyangcheola" was 4.8 MT/ha at our sites under ordinary cultivation (Registration No. 6807).

The "tang[tɑ:ŋ]" in Korean pronounciation means the beverage made of boiled medicinal herbs. The"Jeho-tang", the name of Drink in this abstract, is described in a variety of medical books including the "Dongeui Bogam" as being effective for illness from the summer heat in promoting digestion, curing the heatstroke and bringing it to a halt. The Drink was used as the Royal gifts granted to retainers and royal families on the Day of Dano-festival on the fifth of the fifth month of the year according to the lunar calendar, the items of encouragement for those who worked hard in sacrifices, and the awards for students of Confucianism who were proficient in their learning. The Jeho-tang used in this study was scientifically cooked again after a long time in history through looking at the methods written in the documents concerned with the Drink such as the "Dongeui Bogam" and the "Taste of Korea". In preparation of the medicinal herbs for the Drink, the powder of thinner than 30 mesh of the "Prunus mume", which is a species of Asian plum in the family of Rosaceae, and those of 50 mesh of the "Santalum album", which is the fragrant wood of trees in the genus Santalum and the "Amomum Xanthioides", which is produced in Vietnam and is the name of a kind of herb medicines, being very effective in the desease caused from heatstrare, were used. The sugar concentration of the honey boiled down long time at low heat was $82.43^{\circ}Bx$. When cooking in a double boiler, the inner part of the liquid for the Drink was kept at $80^{\circ}C$ for 12 hours to make it finished in a state of ointment. In the general composition of the finished Jeho-tang, the moisture content was 24.4%, 1.3% of crude fat, 1.4% crude protein and 0.7% ash, along with pH3.2. The acceptance on the whole was come out to be the highest in the sample diluted with the drinking water of 7-fold of the Jeho-tang, indicating that the 7-fold's addition of water was optimum level for drinking. In the Drink cooked by a vaccum pressure extractor for herb medicine, which was developed to improve the art of cooking, the longer the time of pressure was, the less the heterogeneous feeling at tongue was and the more the glossiness of the Drink was. The Jeho-tang cooked under pressure for 7 hours received an excellent evaluation in its acceptability in every way.

Essential oils are fragrant oils extracted from the leaves, stems, peels, petals and roots of aromatic plants cultivated by natural means or using organic agricultural techniques. Essential oils have commonly been used as antibacterial and antifungal agents. In the present study, essential oil was extracted from lisianthus (Eustoma grandiflorum [Raf.] Shinn.) and tested for antifungal activities against three eumycetes (Penicillium pinophilum, Chaetomium glogosum and Aspergillus niger). Lisianthus essential oil showed high antifungal activities against three eumycetes, especially against Aspergillus niger, for which the resulting minimum inhibitory concentration (MIC) was 0.005 mg/ml. In addition, the extracted essential oil was shown to have antimicrobial activity against ten intestinal pathogenic bacteria (Escherichia coli, Salmonella typhimurium, Klebsiella pneumonia, Staphylococcus aureus, Bacillus cereus, Listeria monocytogenes, Pseudomonas aeruginosa, Bacillus subtilis, Enterococcus faecalis and Vibrio parahaemolyticus) according to the disc diffusion method and was also shown to exhibit strong antibacterial activity against an additional three pathogenic bacteria (Bacillus subtilis, Listeria monocytogenes and Vibrio parahaemolyticus). These results indicate that lisianthus essential oil could be used as an antibiotic against harmful bacteria that produce intestinal illnesses. From the present study, we suggest that lisianthus extracts can be utilized as potential antifungal and antibacterial agents and for the development of pharmaceutical and cosmetic products.

A total of 120 pigs (Berkshire) were used to investigate the effect of dietary supplementation with artificial culture medium ot wild ginseng (CMWG) on the fatty acid composition, amino acid composition and sensory characteristics or pork About $60{\pm}3kg$ pigs were randomly assigned to one of four experimental diet groups[(both sexes)${\times}$(C: commercial diet feed; T: commercial diet+1 L CMWG per day for 70 days)]. Pigs were slaughtered at approximately 110 kg live weight, and fatty acid composition, amino acid composition and sensory characteristics were measured in pork loin. The monounsaturated and saturated fatty acid contents was greater in barrow fed a diet containing CMWG than those of the gilt pork and control groups, however the polyunsaturated fatty acid composition decreased. The EAA (essential amino acid) content was lower in pigs fed diets containing CMWG than that of the control groups, whereas the SAA (amino acid with sulfide) and FRAA (fragrant amino acid) contents were higher. The EAA and FAA (amino acid in relation to flavor) contents were lower for harrow than for gilt, however the SAAA (amino acid in relation to saccarinity), SAA and FRAA the contents were higher. Regarding the sensory evaluation of fresh meat, the color of gilt pork increased with diets containing CMWG relative to the control group. Drip loss and the marbling score for pigs fed with diets containing CMWG were higher in barrow than in gilt. The flavor and overall acceptability of cooked meat from the control group was higher for barrow than for silt.

Essential oil is a volatile substance obtained by physically obtaining fragrant plant materials made by one single plant and plant species, and is widely used for cosmetics, fragrances, and aroma therapy due to its excellent preservation, sterilization, and antibacterial effects. When essential oil would undergo the extraction and concentration processes, the agricultural chemicals thereof would be extracted and concentrated only to be harmful to the human body. This study analyzes 320 residual agricultural chemicals concentrated in the essential oil, and to this end, LC-MS/MS and GC-MS/MS are used, while the freezing process is applied instead of the conventional refining process hexane, to improve the preprocessing method. As a result of analyzing the essential oil, such ingredients as chlorpyrifos, piperonyl butoxide and silafluofen have been detected in Basil oil and Clove leaf oil. Hence, it is perceived that the residual agricultural chemicals should continue to be monitored for the essential oil.

In order to extract the essential oil contained in the Elsholtzia splendense Nakai, a fully-bloomed individual was collected and the living body was used for the experiment. Plants were divided into 0.7kg of flowers and 1.5kg of leaves + stems, and extracted by parts and used for scent pattern analysis, and extracted after adding 5kg of outpost for the analysis of essential oil components. Essential oil extraction was performed using the SDE method improved by Schultz et al. (1977), and the extraction time was limited to 1 hour after the material started boiling. The extracted essential oil component was analyzed for fragrance pattern analysis using an e-nose, and the results of analyzing the substance of the essential oil component by GC-MS are as follows. 1. As for the fragrance pattern analysis, in the case of essential oils extracted from flowers, the scent quality was the best at 10-20 minutes, and the scents extracted from stems and leaves were somewhat of poor scent quality, but the fragrance was good at 10-40 minutes. The intensity of scent was the strongest in 10-20 minutes, and the intensity of incense was high even in 30-40 minutes. The scent extracted from the stems and leaves was generally not strong, but appeared high in 10 to 20 minutes. 2. There were 40 kinds of essential oils contained in Elsholtzia splendense Nakai oil. Among them, Mequinol, Benzene, 1,2,3,4-tetramethyl, Elsholtziaketone, and Dehydroelsholtziaketone were identified.

This study was conducted to determine the effect of pH adjustment and the addition of cryoprotectants on the storage properties of chicken breast surimi. Surimi as a control was prepared with Alaska pollack by two times of washing treatment and addition of cryoprotectants(4% sugar, 5% sorbitol and 0.3% polyphosphate). Three types of surimi were manufactured by different cryoprotectant conditions(T1: 5% sorbitol+0.3% polyphosphate, T2: 4% sugar+5% sorbitol+0.3% polyphosphate, T3: 2% salt+4% sugar+5% sorbitol+0.3% polyphosphate) and frozen after adjusting the surimi to pH 11.0. The amino acid and saturated fatty acid composition were significantly higher in the control. EAA(essential amino acid), FAA(amino acid in relation to flavor), SAAA(amino acid in relation to saccarinity) and FRAA (fragrant amino acid) were significantly higher in the control. The TBARS(thiobarbituric acid reactive substances) and VBN(volatile basic nitrogen) were increased with storage times. TBARS and VBN values were significantly higher in the control and T3 than the other treatments. The VBN was significantly higher in control and T3 than other surimi samples. Chicken breast surimi adjusted to pH 11.0 had higher in microorganisms than the control, and T1 sample had the highest total plate count. Sensory evaluations were significantly higher in the control and T3 than the other samples. Especially, the overall acceptability of T3 was similar to the control.

Through literature review and on-site survey of Gimcheon Bangcho pavilion(芳草亭), the features of garden design(庭園意匠) including geographic conditions, landscape modeling of Nujeong(樓亭) and Jidang(池塘, Pond), and scenic interpretations in Nujeong Jeiyoung poetry(樓亭題詠詩) have been carefully researched and the findings are presented below. Bangcho pavilion is located in a village called Wonteomaeul, which belongs to the feng shui state of golden hairpin and floating lotus. It has long been the cultural hub of communication and social interactions among the villagers. The Head House of Jeongyanggong(靖襄公宗宅), the main house(本第) of the Yeonan Yi Clan(延安李氏), is about 150m away from Bangcho pavilion, an artistic space whose landscape modeling is of the form called Nujeong. The name 'Bangcho' reflects the noble man(君子)'s determination: "I yearn for the place where honey parrots fly and the fragrant grass grow." From the two story structure of the pavilion where there is an additional floor installed to the central ondol room by a four-sided subdivision door, one can detect the aspiration of the men for pursuing an open view. One can also observe the efforts in designing the room to be used for multiple purposes from a private place to an office for periodic publication of a family lineage document called "Garyejunghae(家禮增解)". Bangcho pavilion's main sight of interest is Mrs Choi's Pond(崔氏潭), the one and only garden structure that comprises the twin round island of square pond(方池雙圓島) among the existing Jidangs in Korea. In this special Jidang, there are two coexisting islands that represent a well thought out garden facility for symbolizing conjugal affection and unyielding fidelity between master and servent(主從). In addition, the three inflows and one outflow facing the Ramcheon valley is regarded as an ideal garden design optimized for performing the function of a village bangjuk which is the site for undercurrent creation and ecological reprocessing. At present, Giant pussy willow is the only circular vegetation identified in the area of Bangcho pavilion, although this plant species is about to wither away judging from the signs of decrepitude that seems to persist for two out of three weeks. The old pine tree that appears in the 1872 Jeiyoung poetry of Byeongseon Song(宋秉璿) no longer exists. Anjae(安齋) Jang Yoo(張瑠)'s "Eight Scenary on Bangcho pavilion(芳草亭八詠)" and its expansive reproduction "Ten Scenary on Bangcho pavilion(芳草亭十景)" from Gwagang(守岡) Lee Manyoung(李晩永) depict vividly the pastoric scenery of an idyll(田園景) that stretches throughout the natural and cultural landscape of the province of Gimcheon and Guseong surrounding the Bangcho pavilion. The Bangcho pavilion sutra aims to establish Bangcho pavilion and the village of Wonteomaeul as the centre of microcosmos by dividing and allocating its scenic features according to the four seasons and times(四季四時), the eight courses(八方) and the meteorological phenomena, and it is the incarnation(顯現) of landscape perception upon the Byeol-seo Scenic site of Bangcho pavilion, the cultural hub of the region.
